OPINION
Appellant, Scott Peter Zenanko, was convicted by a Crow Wing County jury of the first-degree premeditated murder of Michael Barhorst; the first-degree intentional murder while committing burglary of Thomas Barhorst; the attempted first-degree murder of Cindy Shepard; and first-degree burglary. Pursuant to Minn.Stat. § 609.185(1) (1996), Zenanko was sentenced to consecutive mandatory life terms for the first-degree murders of Michael and Thomas Barhorst, which were to be served concurrent with an executed 48-month sentence for burglary, and a 180-month executed term for the attempted first-degree murder of Cindy Shepard. On direct appeal, this court affirmed Zenanko’s convictions.
See State v. Zenanko,
In September of 1997, Zenanko, now acting pro se, brought a petition for posteonviction relief. In his petition, Zenanko alleged prosecutorial misconduct, nondisclosure of evidence, ineffective assistance of trial counsel, ineffective assistance of appellate counsel, improper sentencing, and improper jury instructions. Zenanko sought a vacation of his convictions, a new trial, an evidentiary hearing, or a modified sentence. The post-conviction court denied all of Zenanko’s motions, except to order the files preserved pending Zenanko’s appeal. The postconviction court ruled that Zenanko’s claims of prosecutorial misconduct, nondisclosure of evidence, ineffective assistance of trial counsel, improper sentencing, and improper jury instructions were all claims that Zenanko could have raised on direct appeal, but did not. The postconviction court also ruled that Zenanko’s claim of ineffective assistance of appellate counsel failed. Finally, the post-conviction court ruled that Zenanko had failed to allege any facts that would require an evidentiary hearing.
The statutory basis for a claim for postconviction relief is found in Minn.Stat. chapter 590 (1996). Section 590.01 provides, in part:
Except at a time when direct appellate relief is available,[ 1 ] a person convicted of a crime, who claims that the conviction obtained or the sentence or other dispositionmade violated the person’s rights under the Constitution or laws of the United States or of the state, may commence a proceeding to secure relief by filing a petition in the district court in the county in which the conviction was had to vacate and set aside the judgment and to discharge the petitioner or to * * * grant a new trial or * * * make other disposition as may be appropriate.
Id.
at subd. 1. A court may dismiss a petition for postconviction relief without conducting an evidentiary hearing if the petition, files, and record “conclusively show that the petitioner is entitled to no relief.” Minn.Stat. § 590.04, subd. 1 (1996);
see also Fratzke v. State,
On review of a postconviction proceeding, our role is limited to determining whether there is sufficient evidence to sustain the findings of the postconviction court.
See Robinson v. State,
On the issue of ineffective assistance of counsel, a defendant must affirmatively demonstrate that his counsel’s representation “fell below an objective standard of reasonableness” and “that there is a reasonable probability that, but for counsel’s unprofessional errors, the result of the proceeding would have been different.”
Gates v. State,
We conclude that, on this record, Zenanko was entitled to neither an evidentiary hearing nor to substantive relief on his claim. Because the record indicates that Zenanko’s claims of prosecutorial misconduct, nondisclosure of evidence, ineffective assistance of trial counsel, improper sentencing, and improper jury instructions could have been raised either at trial or on direct appeal, we affirm the postconvietion court’s order. We also affirm the postconviction court’s determination that Zenanko’s claim of ineffective assistance of appellate counsel is without merit, and that Zenanko failed to meet his burden in order to gain an evidentiary hearing.
As to the evidentiary claims made by Zen-anko in his petition, these claims were addressed on direct appeal. See
Zenanko,
Zenanko’s claims that he received ineffective assistance of trial counsel, improper sentencing,
2
and improper jury instructions could have been raised on direct appeal. Once a defendant has had a direct appeal, “all matters raised therein, and all claims known but not raised, will not be considered upon a subsequent petition for postconviction relief.”
State v. Knaffla,
The only claim properly before us, then, is Zenanko’s claim of ineffective assistance of appellate counsel. Zenanko raises two claims. First, he argues that the state violated the margin requirements for briefs as stated in the Minnesota Rules of Appellate Procedure. This claim is not only meritless but borders on frivolous. Second, Zenanko claims that his appellate counsel should have petitioned this court for rehearing to consider his evidentiary claims. The rule concerning petitions for rehearing provides:
The petition shall set forth with particularity:
(a) any controlling statute, decision or principle of law; or
(b) any material fact; or
(c) any material question in the case which, in the opinion of the petitioner, the Supreme Court has overlooked, failed to consider, misapplied or misconceived.
Minn. R. Civ.App. P. 140.01 (1996).
We considered Zenanko’s evidentiary claims on direct appeal and concluded that “the alleged errors and misconduct, taken cumulatively in the context of the defendant’s tidal as a whole, fall far short of establishing prejudice of the kind warranting a new trial.”
Zenanko,
Affirmed.
Notes
. Because Zenanko had already appealed his conviction, direct appeal was no longer available.
